We　multiplex　20　plane-wave　holograms　in　LiNbO3:Fe:Cu　crystal　with　recording　beams　at　633　nm　and　gating　beam　at　365　nm.　Their　average　fixing　efficiency　reaches　79%,　and　after-fixing　dynamic　range　M/#　is　1.50.　The　effect　gating　intensity,　and　intensity　ratio　of　writing　to　gating　beam　on　two-color　recording　performances　of　multiplexing　holograms　in　LiNbO3:Fe:Cu　crystal　is　investigated.　The　experimental　results　show　that　the　decrease　of　the　intensity　ratio　of　writing　to　gating　beam　and　the　increase　of　the　gating　intensity　at　the　same　time　will　result　in　higher　average　fixing　efficiency　and　dynamic　range.　On　the　other　hand,　the　experimental　results　indicate　that　the　higher　the　intensity　ratio　of　writing　to　gating　beam,　the　higher　recording　sensitivity.
